a BY YTEJ E J0 Patented June 9, 1942 UNITED STATES PATENT OFFICE 1Claim.

This invention aims to provide a novel means whereby a copy holder maybe maintained in a variety of positions on a lintotype machine or anyother similar instrumentality, with a View to presenting the copy inproper position with respect to the operator.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thecope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings:

Fig. 1 shows in front elevation, a device constructed in accordance withthe invention;

Fig. 2 is an end elevation;

Fig. 3 is a rear elevation;

Fig. 4 is a perspective view showing the lazy tongs and attendant parts;

Fig. 5 is a cross section on the line 5-5 of Fig. 2;

Fig. 6 is a detailed sectional view showing a minor modification.

In carrying out the invention, there is provided a track I, which,preferably, is in the form of a bar of circular cross section. By meansof screws 2, the track I is secured to the linotype or other machine,and the track I is provided with rectangular recesses 3, adapted toreceive correspondingly shaped shims 4, which raise the track Isufliciently to allow proper clearance between the device forming thesubject matter of this application and the machine whereon it ismounted. Owing to the way in which the recesses 3 and the shims 4 areformed, the track I will not rotate about a horizontal axis. At one end,the track I has a hole 5, for the reception of one of the securingelements 2, the track being provided at its opposite end with a slot 6,for the reception of the other of the securing elements.

A carriage I i provided, and may be an angle member, including a firstflange 8 and a second flange 9 disposed at right angles thereto. Thesecond flange Q'is provided at its ends with rectangularly disposed earsII], having openings II for the reception of the track I. Theconstruction is such that the carriage 'I may be shifted lengthwise ofthe track I, or be adjusted circumferentially thereof. In order to holdthe carriage I in any position to which it may have been adjusted,either longitudinally of the track I or circumferentially thereof, thesecond flange 9 is provided with releasable holding devices, adapted toengage the track. The holding devices may be set screws I2, threadedinto the flange 9.

A lazy tongs mechanism I4 is provided, and includes first or rear linksI5, having their rear ends connected by headed pivot elements I6 to theflange 8 of the carriage I. The lazy tongs mechanism I4 includes secondor forward links H, connected to the links I5 by headed pivot elementsI8. By means of headed pivot elements I9, the links H are connected to asupport 20, in the form of a rod, disposed considerably ahead of thetrack I.

The numeral 2| marks a copy holder, whereon a combined line finder andpaper retainer 22 is mounted at 23. The copy holder and the line findermay be constructed as desired.

Headed studs 24 project rearwardly from the copy holder 2|, and carryfixed jaws 25, abutting against the rear surface of the copy holder.Cooperating movable jaws 26 are mounted on the studs 24, the jaws 26and. 25 being recessed as shown at 21, to fit closely on the track I. Inthe interest of creating increased holding friction, compression springs28 are mounted on the studs 24, on the pivot elements I9, on the pivotelements I8, and on the pivot elements I6. In View of the showing of thedrawings, it is unnecessary to specify the various parts which are heldintimately and frictionally together by the springs 28.

As shown in Fig. 6, the springs 28 may be omitted, rivets 50 beingrelied upon to afford the necessary friction between parts such as I5aand I'Ia. The following adjustments, governing the position of the copyholder 2| with respect to the operator, are possible: a movement of thecopy holder lengthwise of the support 20, as shown by the arrows A inFig. 3: a front to back swinging movement of the copy holder on thesupport 20, as shown by the arrows B in Fig. 2: a front to backadjustment of the copy holder, indicated by the arrows C in Fig. 3: amovement of either end of the copy holder, toward and from the track I,as indicated by the arrows D in Fig. 3: a shifting of the carriage I andthe copy holder 2|, lengthwise of the track I, as indicated by thearrows E in Fig. 3: and a movement of the carriage 1 and the parts whichit supports, circumferentially of the track I, as indicated by thearrows F in Fig. 2.

From the foregoing, it will be observed that the device is capable ofmeeting any reasonable demand that may be made upon it, so far as theposition of the copy holder 2| with respect to the operator isconcerned.

Owing to the many adjustments of which the copy holder 2| is capable,eye strain will be avoided, and glare, shadows and cross-lights will beavoided.

Having thus described the invention, what is claimed is:

In a copy rack, a copy holder, a rod-like, approximately-horizontalsupport, spaced connectors joining the holder with the support forgoverned rocking movement transversely ofthe axis of the support, asingle pair of forward links, a single pair of rear links, pivot meansconnecting the forward end of each rear link with the rear end of oneforward link, for movement in a plane parallel to the support, and topermit the pivotally connected links to fold laterally in oppositedirections, means for pivotally joining the forward ends of the forwardlinks to the support at spaced points located between the connectors,for movement in a plane parallel to the support, a carriage, means forpivotally connecting the rear ends of the rear links to the carriage atspaced points, for movement in a plane parallel to the support, a trackwhereon the carriage is mounted to slide laterally and to swingvertically, the track being of such length that the carriage may have awide range of lateral adjustment thereon, means for holding the carriagereleasably fixed with respect to the track, and means for mounting thetrack terminally on a linotype machine, in a practically horizontalposition.
